Enhanced CMake support

[cdglove]

Enhanced @Amorph initial CMake support with support for other platforms. Also added x64 support to timing.cpp

• Add platform support
• Add option to copy built files to win32 directory
• Switch to freeglut (adds win64 support)
• Fix a bug where cmake include paths weren't correctly setup in demo exes.
• Add new win32 binaries built against freeglut.
• Add x64 support to timing.cpp

I recommend deleting the current build files and using only cmake. I will prbably make that change and submit another PR.

Is there a way I can get your commits without the author merging?

[cdglove]

Yes, just pull from my repository:
git pull git@github.com:cdglove/cyclone-physics.git cmake_support
or
git pull https://github.com/cdglove/cyclone-physics.git cmake_support

I pulled this request locally, but got an error when run CMake:
CMake Error at src/demos/CMakeLists.txt:11 (file): file COPY given no DESTINATION
@cdglove Do you know what's this error

You could try at line 11:

configure_file(${CMAKE_SOURCE_DIR}/contrib/freeglut/bin/x64/freeglut.dll ${CMAKE_CURRENT_BINARY_DIR}/freeglut.dll COPYONLY)

and likewise for line 15.

I haven't tested this but this is how I usually copy files in CMake.
